After reincarnating, I became a second generation villain - Chapter 34 My Son Is Actually A Martial Emperor?

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

The legendary mana finally reached planet Earth, causing all living things to officially enter the path of evolution.

In the rural northeastern mountainous regions stands a tiny Buddhist temple, named One Finger Temple. It isn’t a large one but it is extremely miraculous.

The temple has rice that emanates an aromatic fragrance.

The temple has sweet and refreshing water that rivals ambrosia.

The temple has Buddhas that grant wishes to the sincere.

The temple isn’t large but it has everything. The temple isn’t large but it has flourishing incense offerings that far exceed all temples. The temple isn’t large but it attracts both citizens and foreigners that line up overnight…

The temple has a bald but handsome monk. Every day, he would bawl, “I want to renounce asceticism! I want to marry a chick that’s not too pretty, have a cute baby, and lead a stable life!”

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.
